Mitochondria play an important role in neuronal apoptosis caused by cerebral ischemia. Researchers at the Affiliated Hospital of Qingdao University, China discovered transient ischemia led to cell apoptosis in the hippocampus and changes in memory and cognition of aged rats. Differential proteomics analysis suggested that this phenomenon may be mediated by mitochondrial proteins associated with energy metabolism and apoptosis in aged rats. This study reported in the Neural Regeneration Research (Vol. 9, No. 11, 2014) provides potential drug targets for the treatment of transient cerebral ischemia-reperfusion injury.
